I Want to Get This Sound and Have No Clue How

Hey guys,

I’m working on a song of mine and trying to duplicate an effect to no avail. The sound I’m going after is this

The sound I’m after comes in around the 50 sec mark.

I’m not trying to duplicate the synth here, just that “wah-ing” whining sound its making. I can’t tell if its an LFO trick or a formant filter or something else entirely but I’d really like to recreate it if possible.

Thanks in advance if anyone has any tips!

wah wah pedal

Think i figured it out. Mod envelope on a hi pass filter with automation on the cutoff
